Looking for opinions here!

I noticed most everyone with a toyota and a weber carb has the 32/36 mm - I talked with the Weber folk and they recommended the 38mm because I will be at elevation and often driving hills/ dirt roads. I won't be doing a ton of wheeling though. Mostly, I dd this truck with very occasional trails. But I do live 6 miles (min.) down dirt road with some big hills for my little 22r. The weber guy was convincing that the larger carb was the way to go. Does anyone have experience with the 38mm, does it just have bigger air intakes or what makes it a bigger carb? I would love to improve my gas milage rather than hurt, even if it isn't the best for performance. Any suggestions are appreciated!!

from what I gather the 32/36 has a bit better fuel economy than stock, and a lot better than the 38. No personal experience, but I have known a few people go the 32/36 route and love it. One thing to remember is the 32/36 opens one barrel than the other, the 38 opens them both at the same time, thats where the fuel economy difference comes from.

Ahh, thanks rowdy, that is what I was looking to hear. I really don't want my gas milage any less than it is now!! I was wondering why no one seemed to have the 38 on their Toyota.

this has been a big debate every where stock vs webber 32/36 vs 38
my honest opinion is leave the stock carb
get a header from lc engineering and 2.5 in exhaust ud be amazed on how much that will open that little eninge up
i did that with mine and being 4wd and geard 5.29 and running 35s im currently getting 20-25 mpg depending on how and where im driving

Thanks.. this is good info. I have been looking into headers as well. I was a little worried about the rebuild-ablity of my stock carb although because someone before me in ownership bent the choke. Plus, I live where it gets pretty cold in the winter, and this winter it was not running well in the cold. Thanks again for the advice.

I had a 32/36 and a header on my 89 2WD and it pulled pretty good. Of course, that was at sea level.

I disagree with the above - the carb made a huge difference on mine, much bigger than the header, but my stock carb was going bad, and I had a cheapo Pacesetter header. Back then, a Weber was cheaper than a rebuilt stock carb, I understand that's not the case any more ...

Get on TTORA and ask vwfastg60 what he has - I think he has the Weber 38 and has had problems at low speed (wheeling)

I had a Weber 38 on my 87 22R. With all the goodies (dist recurve, header, exhaust, intake, cam, valve springs ect) It ran great at all speeds for me. Unfortunately I did not do a whole lot of crawling, was mostly highway driving. Fuel Economy.. I think i would have used less gas if I hired somebody to stand on the intake and pour the fuel in with a 5 gallon bucket. But, when you stepped on the skinny pedal the truck did move quite well What elevation are you planning on running the truck? I had to re-jet the 38 to make it run at my elevation (approx 2000ft)

thats funny cause i though all 87s and up had efi an 89 carbed come awn


and back to the stock rebuild u can get one from a guy who sells them for about 84.99 plus shipping

I live in Colorado, so my house is about 7,000 ft above sea level and if I do any wheeling it will be way up in the mountains (up to 12,000 ft) because I will be trying to access peaks. The guy at weber said I would need different jets. But I don't think I am interested in the fuel usage you descibe... even if my truck flew up hills (I will be very stoked to go the speed limit up the passes!)

Workhorse

ouch yea that's pretty high definitely going to need a re-jet. Personally i would recommend the 32/36 for the fuel economy. When I built my 87 it was back in 2000 and gas was no where near as expensive as it is now I got the 38 dirt cheap from a friend and the rest of the modding to make it *go up the hill* insued My 22r would pull any hill i put in front of it at 60mph no problem. The hills in Colorado I'm sure are steeper than they are here tho. (Mt Hood OR)

If you want mpg, you can forget about it with a 38. it goes right out the window!
if you want power and better low end,it has it all.
I had one of these on my last truck(82 with 22r bored .40 over and shaved head 15 thou) and it ran like a pro!.
however, i do wish that i didnt have it on there because i did a lot of driving myself and it was not good for highway use or short trips.
also on cold mornings it seemed to take longer than usual to get up to speed. I.E. had to wait longer for it to warm up.

Read my post again genius.

22R (carbed) was available in the 2WD until at least '91 ...

84socal

oh so ur one of those i know every thing about everything guys huh thats cool i hope that works out for u

tc

Not everything about everything, but I for darn sure know I owned an '89 2WD and it was carbureted. Why would I lie about it?

Are you just being a troll?

great thread guys! I was just looking into a 32/36 and wondered if there was even a difference vs. stock....then I found the 38 which I had no idea of..it sounds like something im looking for..more power, crisp throttle response/low end...how is the 32/36 for this sort of application?

808yotapma

I know this doesnt mean much to you guys up there in the mainland but ive had a good few of my friends put 38 carb on there built and stock 22r and they say better power better gas mileage and all around better response. .but thats all down here in hawaii...going up to the mountains 6000 to 8000 ft. just have to adjust the distributor. .this is going to be the first 38 im going to put on my yota and cant wait to see what kind of difference it makes...now with that said i see a lot of bad talk with pace setter headers why dont people like em?

What are the specs on your engine? I have a completely rebuilt 22R bored 0.020" over with a new stock cam, new stock valves, completely desmogged, LCE spiral Weber adapter, Rock Ripper stainless headers, 2.25" exhaust, Thrust muffler and no cat. I originally had a 32/36 and I could never get it tune and jetted just right - the engine was just simply wanted more fuel. I ended up going with a 38 and I haven't looked back. The is definitely more low end power and torque and the high end remainder about the same. I lost about 1.5 MPG going to the 38 from the 32/36 but that still puts me in the neighborhood of 20MPG. I would say that on a bone stock 22R, go with the 32/36 but if you have any or are planning any engine upgrades then go with the 38. Just make sure you get a genuine Weber carb. Pay the little bit extra and order it from LCE, Weber Carbs Direct or Carburetion.com. You will regret not getting a genuine Weber carb

I have a 1980 4X4 with the 20R. I put a 38 and a header on at the same time and I am very satisfied with it.
